The crushing mechanism is provided to realize the function of crushing the stone;

[0023] The inner wall of the housing 1 is rotatably connected with a buffer plate 11, and the buffer plate 11 is located between the crushing mechanism and the mounting plate 17. The buffer plate 11 is arranged in the housing 1 to receive the crushed stone, so as to prevent the screen 16 from being damaged by excessive impact force when the stone falls.

[0024] The two side walls of the casing 1 are fixedly connected with mounting blocks 13, and the mounting blocks 13 are embedded with fixedly connected damping blocks 15. The lower ends of the buffer plates 11 are fixedly connected with connecting blocks 12, and buffer springs 14 are arranged between the connecting blocks 12 and the inner side walls of the casing 1. The connecting blocks 12 and the casing 1 are fixedly connected via the buffer springs 14.

The collecting box 6 is used to collect processed stones, and the foot supports 23 play a supporting role for the device.

[0028] Working principle: When the construction waste is processed for the second time, the construction waste is introduced into the casing 1 through the guide plate 5, and the two crushing rollers 10 are rotated by the first driving motor 25 to crush the construction waste. The crushed particles fall on the buffer plate 11, and the buffer plate 11 buffers the crushed stones under the effect of the mounting block 13 and the damping block 15. The buffer plate 11 guides the crushed stones and buffers the falling of the stones as quickly as possible, so that the crushed stones fall on the screen 16, and prevent the screen 16 from being damaged by excessive impact when the stones fall, which meets the diameter size. The stones fall into the collecting box 6 through the sieve holes on the screen 16 for collection, and the second driving motor 3 drives the rotating rod 19 to drive the cam block 20 to rotate. The cam block 20 intermittently squeezes the mounting plate 17, causing the mounting plate 17 to shake, and the stones that do not meet the size and stay on the screen 16 are shaken into the return box 2 through the through groove 7. The second driving motor 3 drives the conveying screw 8 in the return box 2 to convey the stones that do not meet the size to the guide plate 5 again, and the stones that do not meet the size are crushed for the second time until all the stones meet the size standards. There is no need for manual screening after processing, which improves the production efficiency of recycled stone.
